C Flanigan/F​ilmMagic(LOS ANGELES) -- Jonah Hill says he wanted to be a rapper just like Eminem when he was a teen in high school.

In an interview with Parade magazine to promote his new movie, 21 Jump Street, Hill recalls, "I had bleached hair and wanted to be Eminem badly!"

Hill's Jump Street co-star, Channing Tatum recalls his high school days, saying, "I played football and wore a letterman jacket a lot. But I could not wait to get out of high school. When graduation day came, I could not get out fast enough. It wasn’t a bad experience; it wasn’t just something I enjoyed."

When asked if anything surprises him about today's teenagers, Hill says, "This is going to make me sound 150 years old, but it's technology. They live their lives through Facebook and stuff. And I don’t live my life through that at all. I prefer talking."

The pair portray undercover cops who pose as teenagers to track down a high school drug ring. 21 Jump Street opens nationwide March 16.
